CQ'FIQN-SEEDHULLER.

SPECIFICATION forming part of Letters Patent NO- 477,997, dated June 28, 1892. Application filed December 24, 1890. Serial No. 375,687. (No model.)

To all whom it may concern.-

Be it known that I, JAMES J. FAULKNER, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Cotton Seed Hullers, of-

which the following is a specification.

The invention relates to a machine for re moving the hulls from the cotton-seed Without crushing the seed or breaking the oil-sacks therein; and the invention consists in certain novel features in the construction of such apparatus, to be hereinafter more fully described, and specifically pointed out in the claim.

In the accompanying drawings, Figure I rep- 1 resents in axial section a hulling-cylinder constructed in accordance with my invention. Figs. II, III, and IV represent, respectively, the outside washer, the saw, and the inside fibrous packing-washerjwhich when mounted upona shaft and-"secured by suitable nuts constitute my improved cylinder. Figs. V, VI, and VII represent three arrangements or forms of machine embodying my invention. Figs. VIII and IX show. concaves having different forms of surface.

1 represents the shaft, 2 the jam-nuts, 3 the the outside clam ping-washers, 4: thesaws, and 5 the inside paper packing-washers, which together constitute'my improved cylinder. The shaft l is of steel or other suitable material and has threadedportions near its opposite ends for thereception of the screw jam-nuts 2. The clamping-washers, saws, and packingwashers have perforations 6, which adapt them to fit snugly upon the shaft 1, and they may be keyed upon the shaft by notches 7, though i this will not ordinarily be necessary. In setting up the cylinder, one of the jam-nuts bejIX represents a surface covered with a number of closely-arrangedtransverse saw-edges.

ing in place, the clamping-washer is placed on and then the saws and packing-washers suc-' cessively passed over one end of the shaft un-. til the cylinder is formed of the desired length, i when the other clamping-washer is placed on and the other jam-nut screwed into place until all the disks are clamped tightly together. A cylinder may be constructed of any desired length in this manner and its distance fromi the ends of the shaft regulated to suit the form of machine. It is important that the washers 5 be made of paper, as I have found this to 'be the most satisfactory material, owing to its small cost, light weight, and durability.

In Fig. V is represented a machine having a feed-roller 8 of any desired construction and three co-operating differential hulling-cylintween the fast cylinder andifinishing-cylinder.

In Fig. VI the arrangement is similar to that described with reference to Fig. V, except that the finishing-cylinder 11 is replaced by a stationary concave 12, concentric to the fast cylinder. The concave is for many purposes the equivalent of the finishing-cylinder. If preferred, this concave l2 may be pivotally supported and'kept to its work by a spiral spring in the manner shown in Fig. VII.

In Fig. VII is illustrated a similar arrange ment. I-Iere but one cylinder is used, and in connection withit the complementary working surface consists of a concentric concave 13, mounted upon trunnions 14, held to the cylinder by a spring 15 and regulated by a l screw 16.

In Figs. VIII and IX are shown two different forms of corrugation for the concaves 12 and 13, Fig.VIII representing a surface formed of a number of intersectingplanes, while Fig.

The latter form is closely allied in the effect produced to the saw-toothed cylinder 11 described in Fig. V.-

The casing is formed with a hopper 20,

within which the feed-roller rotates with expanded portions 21 22, within which the slow and fast hulling-cylinders are located, and with a drop portion 23 for the finishing-cylinder and for the conveyor 24, as shown.

IOO

beneath the expanded portions, the feed-roller located within the hopper, the slow and fast cylinders located within the expanded portions, and the finishing-cylinder and the conveyer located in the drop portion, substantially as described.
